This example creates an interactive map of the world using a Natural Earth projection and SVG rendering. It loads geographic data from the world-atlas TopoJSON and TSV datasets, then uses d3.geoPath and d3.geoNaturalEarth1 to draw country boundaries and fill them with white. Hovering over a country highlights it in light grey, and each country displays its name as a tooltip via a title element. The code also applies a light blue background to the page.
